Application filed November 1,1191?. Serial No. 199,736.

To all w/Lom t may concern.'

Be it known that I, FREDERICK M. VHYTE, a citizen of the United Statesof America, residing at Tarrytown, in the county of Westchester andState of New York, have invented certain new and useful Improvements inCar-Roofs, of which the following is a specification, reference beinghad therein to the accompanying drawings.

The invention relates to car roofs, of that type in which theload-sustaining roofing sheets are relatively movable to permitadliustment to distortions in the car frame. It is the object of theinvention to provide a more thorough weather-proof joint betweenadjacent members without in any way interfering with their freedom ofrelative movement. To this end the invention comprisesV the constructionas hereinafter set forth.

In the drawings:

Figure 1 is a sectional of a portion of the car roof, improvedconstruction;

Fig. 2 is a similar view, showing a slight modification Fig. 3 is adiagrammatic view Ashowing a portion of the car roof of Fig. 1.

A and are portions of two adjacent roofing sheets, which may besupported and secured down upon the roof frame (of which only across-section of a carline H is shown), in any suitable manner. Theopposite side edges of these sheets are provided with upstandingflanges, a single flange C being arranged at one side, and an open,returnbent flange D being arranged at the opposite side. Thus, when thetwo sheets are laid ad'acent to eachother, the returnbent flange y willembrace the flange C, permitting freedom for relative movement. 4

The construction as thus far described will not be thoroughlyWeather-proof, as the rain, cinders, etc., will find access to theinterior of the car, passing under the returnbent flange D and blowingover the flange C. To render the structure com letel weatherproof, Iprovide a cap mem er` which is of' an inverted U y p Ereferably providedwith foot flanges F and One of these flan es is secured to one of thesheets A or B y riveting or otherwise, while the other flangel bearsupon the d'acent sheet. The U-'shap'ed'rportion is of cient width toprovide clearance on opperspective view showing my or returnbent4 form,and isA posite sidesI of the returnbent flange D, so as not to interferewith freedom of movement. (l is a securing device attached to the sheet,which is free from the member D and is adapted to hold the flange F ofsaid member down upon said sheet. As shown in Fig. 1, the member Gcomprises a flange extending parallel to the edge of the sheet andriveted or otherwise secured thereto, a portion of the Harige being bentupward slightly to form a groove for receiving the flange F. In Fig. 2,a modified construction is shown. where a series of' spaced clips (lrare substituted for the continuous strip.

In use, the construction above described will very thoroughly excludethe weather, while at the same time the sheets are freely movable. Theweather-proofing is due to the fact that any Water which may force itsway beneath the flanges F and F will only enter the enlar ed spacebetween the U-shaped member 4 and the returnbent -flan e D. Even in casethe inner pressure is su cient to carry the water upward, it willstillbe excluded from entrance into the car by the returnbenf. flange.

The construction described is applicable to various constructions of carroofs, but is particularly advantageous with that type in which theroofing sheets are rigidly attached to supporting carlines but arepermitted freedom of movement in relation to each other. Thus, as shownin F ig. l, H are carlines, extending centrally ofl the sheets A and andriveted o`r otherwise rigidly secured thereto. The weather-proof jointis thus arranged midway between carlines and will permit of any relativemovement occasioned by the weaving of thecar frame.

lVhat I claim as my invention is 1. In a car roof, the combination withadjacent relatively-movable roofing sheets, of an upstanding flange onthe edge of one of said sheets, an open returnbent flange on theopposite sheet embracing said upstanding flange and providing clearancefor movement thereof, and a member of returnbent` fform embracing saidfirst returnbent flange with clearance for relative movement, saidsecond returnbent flange being secured to one of the sheets. y l Y y 2.In a car roof, the combination with rela-` tively-movable roofingsheets, of an`u standingv flange at the edge of one of said sheets, areturnbent flange at the edge of the adjacent sheet embracing saidupstanding flange with clearance for relative movement, and a member ofreturnbent form embracing said first-mentioned returnbent flange, withlreedoni for relative niovement, said second flange being secured to thesheet having the upstanding flange.

3. In car roof, the combination with adjacent relatively-movable roofingsheets, of an upstanding flange along the edge of one of said sheets, areturnbent flange along the edge of the adjacent sheet embracing theupstanding flange Withl clearance for relative movement, a secondreturnbent or inverted U-shaped member embracing said first-mentionedreturnbent flange with clearance for relative movement. said secondmember being provided with foot flanges resting upon the respectivesheets, one of said foot flanges being rigidly attached to the sheet onwhich it rests, and means for holding down the opposite foot flange uponthe sheet on which it rests.

4f. In a car roof, the combination with relatively-movable adjacentroofing sheets, of an upstanding flange along' the edge of one sheet, areturnbent flange along the edge of the adjacent sheet embracing theupstand- -ing flange, with clearance for relative movement, an invertedU-shaped or returnbent member embracing said first-mentioned returnbentflange, with clearance for relative movement, said second member beingprovided With foot flanges resting upon the respective sheets, one ofsaid foot flanges being rigidly attached to the sheet having saidupstanding flange, and means for holding down the opposite foot flangeupon the sheet having said returnbent flange.

5. In a car roof, the combination with relatively-movable adjacentroofing sheets, of an upstanding flange along the edge of one of saidsheets, an open returnbent flange alon the edge of the adjacent sheetembracing said upstanding flange, with clearj ance for relativemovement, an inverted U- shaped or returnbent member embracin saidfirst-mentioned returnbent flange, wit clearance `for relative movementand provided With foot flanges for resting upon the respective sheets,one of said foot flanges being rigidly secured to the sheet having saidupstandin Y flange, and a strip secured to the opposite sheet, having aportion overlapping the other foot flange, for the purpose described. jl

GLIII a car roof, the combination with carlines, of roofln sheetsrigidly secured to the respective car ines and extending adj acent toeach other, an upstanding flange on the edge of one of said sheets, anopen returnbent flan e u `on the edge of the adjacent sheet',emV rac ngsaid upstanding flange,

. with freedom for. relative movement, a returnbent or inverted U-shapedmember enibracing said first mentioned rcturnbent flange with clearancefor relative movement and provided with foot flanges resting upon therespective sheets, one ol' said flanges hving rigidly attached to thesheet on which it rests, and means for holding down the opposite flangeupon the sheet on which it rests, permitting relative movement.
